Abstract: An X-ray image apparatus (100) for imaging an object under examination (101), the X-ray image apparatus (100) comprising an X-ray source (103) adapted for generating an X-ray beam (104) to be directed to the object under examination (101), a dose measuring device (106) for measuring an X-ray dose of the X-ray beam (104) in at least one selected (110, 112) of a plurality of measurement fields (108 to 114) after transmission of the X-ray beam (104) through the object under examination (102), and an illumination device (115) for illuminating a surface portion (117) of the object under examination (101) which surface portion (117) is indicative of the at least one selected (110, 112) of the plurality of measurement fields (108 to 114).

Abstract: A method and an assistance system (20) plan geometrical imaging parameters like the active dose-measuring-field (29) and/or the opening of a collimator (12) of an X-ray device (10). An optical image (27) of a patient (1) on a table (2) is generated by a camera (21) and transferred to a computer (25). The computer (25) then overlays said optical image (27) of the patient (1) with a graphical representation of the geometrical imaging parameters, for example with a drawing of the available and/or activated dose-measuring-fields (28, 29). The user may thus control and interactively select values of the imaging parameters on the overlay image.

Abstract: The invention relates to a diagnostic X-ray system which comprises notably a mobile X-ray apparatus (10), a mobile data terminal (30) and a data processing unit (20) for the images acquired by means of the X-ray apparatus (10). The system is characterized notably in that the parameters of an X-ray exposure formed by means of the X-ray apparatus (10) are transmitted, preferably in a wireless fashion, to the mobile patient data terminal (30) in which they are combined with patient data entered by a user as well as with an identification number of the image cassette on which the image is stored, read by means of a bar code scanner (306), so as to form a patient data set. Such a patient data set is then transmitted to the data processing unit (20) in which it is supplemented with the image data which is read from the image cassette so as to be processed. It is thus simply possible to combine all relevant data of an X-ray exposure with one another while eliminating any source of errors at least substantially.
